While looking for a topic for an article on Philly cheese steaks, I found this one. It does not focus entirely on the sandwich, rather it does state that you can get one anywhere in the US, which was one of my questions from class. Why are there always
Philly cheese steak restaurants outside of Philadelphia?

I thought that this article would help in my research as to why Philly cheese steak sandwiches are so popular. It shows the importance it has to the city and why the sandwich is so good.
